The 6.2L EcoTec3 L86 V8 engine launching now as an optional powertrain for the 2014 Chevrolet Silverado 1500 and 2014 GMC Sierra 1500 is a beast of a motor, at 420 horsepower and 460 lb-ft of torque — the strongest in its class currently. The tradeoff, of course, is that it’s thirstier than the 355 horse, 385 lb-ft 5.3L V8, but not by much, as we’ve found out with official EPA mileage figures released today.
Specifically, the EPA estimates for the 6.2L K2xx trucks are rated at 15 mpg city and 21 mpg highway for 2wd models, and an incrementally lesser 14 mpg city and 20 mpg highway for the 4wd models. Compared to the other big engines offered by Ford and Ram, the gas mileage of the new 2014 GM 6.2L trucks is at the top, while providing significantly more power.
